I happy to say that I have a good chunk of my sites up and running on a my EC2 instance. Site performance is pretty good compared to what it was. The only hiccup was some broken links due to a change in permalinks. Additionally, my adsense plugin what causing an error with yoast xml sitemaps. I changed to a different adsense plugin and all was fixed
Managing the Vhosts in Apache is pretty easy, but a little time consuming when setting up the sites.
My next challenge is figuring out mod_rewrite for some of the landing pages.
